UNITED STATES FREDERICK FRANKLIN DIER, OF OTTAWA, ONTARIO, CANADA.

HEATING MEANS FOR LIQUID FUELS.

Application filed February 18, 1922.

To all whom it may concern:

Be it known that I, FREDERICK FRANKLIN DIER, a subject of the King of Great Britain, of the city of Ottawa, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Heating Means for Liquid Fuels, of which th following is a specification.

This invention relates to improvements in heating means for liquid fuels, and particularly such heating means as may be used to heat the fuel between the source of fuel supply and the cylinders of an internal combustion engine, and the objects of the invention are to enable an engine of this charnote! to be started with facility in any and particularly cold weather. Further objects of the invention are to provide a simple and effective device of this character which may be readily installed with any desired type of carburetor and which will be operated to preheat the fuel for the purpose of facilitating combustion thereof. Further objects still are generally to improve and simplify I the construction of the device to better adapt the various parts to perform the functions re uired of them.

t consists essentially of the improved construction hereinafter described in detail in the accompanying specification and drawings.

In the drawings:

Figure l is a sectional elevation of a carbureter having my improved device attached thereto.

Figure 2 is a sectional elevation of the heating device alone.

Figure 23 is a sectional elevation showing an alternative method of attaching the heating device.

In the drawings, like characters of reference indicate corresponding parts in all the figures.

Referring to the drawings:

A indicates a carbureter of any well known and convenient type having a conduit 10 for the supply of liquid fuel such as gasolene, an air intake conduit 11 and a mixing conduit 12 leading to the engine manifold, all of which may be of any well known or convenient type. A suitable form of float valve may also be provided contained in the chamber 13.

B indicates my improved heating chamber comprising a heating element 14 designed to be immersed in the liquid fuel Serial No. 537,632.

contained in the chamber 15, the upper part of which may be provided with a conical head 16 having a threaded neck 17 which may extend into a casing 18 of the carbureter in the form shown in Figure 1, opening into a passageway 19, which leads from the float valve chamber 13 to the vaporizing device 20. The heating element 14 is supported on a suitable plug or bushing 21 having screw threaded engagement with the internally screw threaded end of the casing 15 which is cylindrical in form. The central part of the bushing 21 is formed with a perforat-ion 22 through which an insulating bushing or washer 23 extends carrying a pin 24 onnected to one end of the resistance 14 which is formed from suitable electric resistance wire of such size as to be heated to desirable heat by the current supplied the end of the coil by being conveniently connected to the pin 24 by a nut 25. The coil 14 is of inverted V shape and the opposite end of the coil to that connected to the pin 24 is suitably grounded by being connected to the side of the casing 15. The lower extremity of the pin 24 is screw threaded and provided with a terminal binding post 26 having a transverse perforation 27 through which a connecting wire may extend, the connecting Wire being designed to be held in the perforation by a set screw 28 extending axially through the end of the binding post, the binding post itself having screw threaded engagement with the pin 24 and being spaced from the bushing 23 by a washer 29. it will be seen that in this form of the invention, the chamber 15 will be filled with gasolene or other liquid fuel from the conduit 19 and when the heating member 14 is heated, the gasolene will be heated and will partially vaporize and it will rise upwardly and co-mingle with the supply passing to the vaporizing device, thereby conveying heat units to the cylinder of the engine and facilitating combustion of the combustible mixture.

It will be understood that the terminal wire connected to the binding post 26 will extend to one pole of a suitable battery, while the opposite pole will be connected to a suitable switch provided on the dashboard of the car which, when operated, will complete the circuit through the coil 14 and cause the same to be raised to desirable heat.

In the alternative form shown in Figure 3. an auxiliary supply conduit 30 is provided be attached to any malite of carburetor and may be placed in any desired location in the fuel supply conduit.

As many changes could be made in the above construction and many Widely different embodiments of my invention Within the scope of the claims, constructed Without de-v parting from the splrit or scope thereot, it 15 intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limiting sense.

What Iclaim as my invention is:

1. A device ofthe character described, comprising a cylindrical liquid fuel chamber formedwith a conical upper part having a threaded neck, a threaded plug closing the opposite end of the neck, aninsulating; bushing in the plug", a terminal member extending through the bushing, a heating coil of inserted V-shape connected to the terminal member, the heatingelement carrying plug being adapted to be ren'iovable for drainage and cleansing purposes, a binding; post on the terminal member, and a set screw on the binding post.

2. A device of the character described,

comprising a cylindrical. liquid fuel chainber, formed with a conical upper part having a threaded neck, a feed pipe leading; from the fuel supply'to the cylindrical fuel chamber, a threaded plug; closing the opposite end of the neck, an insulating bushing in the plug, a terminal member extending through the bushing, a heating coil of inverted V-shape connected to the terminal member, a binding post on the terminal member, and a set screw on thebinding post. 3. A device of the character described, comprising a cylindrical liquid fuel chamber formed With a conical upper part, having a threadedneck, a feed pipe leading; from the fuel supply to the'cylindriml fuel. chamber, a threaded plug closing the oppo site end of the neck, an insulating bushing in the plug, a terminal member extending through the bushing, a heating (oil of inverted V-shape connected to the terminal member, the heating element carrying plug being adapted to be removable for drainage and cleansing purposes a binding post on the termnialmember, and a set screw on the binding post.

In witness whereof I havehereunto set my hand in the presence of a Witness.

FREDERICK FRANKLIN DUDE.
